HBO executives say they are "absolutely interested" in making follow-up to the hugely popular Sex and the City movie.

"Everybody came away feeling very excited by [the first film's] quality and its success, so that always invites the possibility of a continuation," HBO co-president Richard Plepler told PEOPLE Thursday after the network's session at the Television Critics Association's press tour.

Will it actually happen?

"It's really up to [director] Michael Patrick [King] and Sarah Jessica [Parker] and the rest of the girls," he said. "But do I think at some point in the next four to five years there's a likely possibility? Yeah, I think there's a likely possibility."

Jennifer Hudson, for one, is ready to reprise her role.

A sequel is "not out of the question," she told PEOPLE Thursday night at London's Keep a Child Alive fund-raiser hosted by Alicia Keys. "I would love to be a part of that."

Me too - I actually *had* to see it 3 times! I saw it on the Sunday of the opening weekend because I couldn't wait...then I saw it as part of my friends bachelorette party, and then I had to go with Matie because he was dying to see it too! It's just as good each time
